چکیده انگلیسی
Ultrafiltration and nanofiltration of spent sulphite liquor (SSL) has been employed to evaluate the simultaneous production of lignosulphonates and bio-based succinic acid using the bacterial strains Actinobacillus succinogenes and Basfia succiniciproducens. Ultrafiltration with membranes of 10, 5 and 3Â kDa molecular weight cut-off results in significant losses of lignosulphonates (26-50%) in the permeate stream, while nanofiltration using membrane with 500Â Da molecular weight cut-off results in high retention yields of lignosulphonates (95.6%) in the retentate stream. Fed-batch bioreactor cultures using permeates from ultrafiltrated SSL resulted in similar succinic acid concentration (27.5Â g/L) and productivity (0.4Â g/L/h) by both strains. When permeates from nanofiltrated SSL were used, the strain B. succiniciproducens showed the highest succinic acid concentration (33.8Â g/L), yield (0.58Â g per g of consumed sugars) and productivity (0.48Â g/L/h). The nanofiltration of 1Â t of thick spent sulphite liquor could lead to the production of 306.3Â kg of lignosulphonates and 52.7Â kg of succinic acid, whereas the ultrafiltration of 1Â t of thick spent sulphite liquor using a 3Â kDa membrane could result in the production of 237Â kg of lignosulphonates and 71.8Â kg of succinic acid when B. succiniproducens is used in both cases.
